site:docs.github.com/en/actions push event branch deletion branches filter head_commit null GitHub Actions workflow syntax

💡 Result:

When a branch is deleted in a GitHub repository, it generates a push event where the head_commit SHA is null (often represented as a series of zeros, e.g., 0000000000000000000000000000000000000000) [1]. Because this push event technically involves a change to the repository refs, it can trigger workflows configured with the push trigger [1][2]. In this scenario, the head_commit object in the GitHub Actions event context (github.event.head_commit) will be null [1]. If your workflow relies on accessing properties of the head_commit (such as the commit message or author), the workflow may fail unless you include a conditional check to verify the existence of the commit object [3]. You can prevent workflows from running on branch deletions by using a filter or conditional logic within your workflow configuration: 1. Using a conditional step: You can skip specific steps in your job by adding an if conditional that checks if the commit SHA is present: if: ${{ github.event.head_commit!= null }} 2. Using workflow filters: While you cannot directly filter out branch deletions in the push event trigger syntax using standard branches filters, you can structure your workflow to handle the event type appropriately or rely on the fact that GitHub Actions workflows triggered by deletions may behave differently regarding the available refs [1]. For operations specifically related to branch deletions, it is recommended to use the delete event trigger rather than the push event, as the delete event is explicitly designed for this purpose and provides a distinct webhook payload [1]. If you use the delete event, you can configure your workflow to run only when a branch is deleted [1].

Citations:

Exclude branch-deletion pushes.

push.branches: ['**'] does not test github.event.deleted. A branch deletion can therefore run this job with github.event.head_commit == null and no commit message. Add github.event.deleted == false to the job condition.

-    if: ${{ vars.PUSH_EMAIL_ENABLED == 'true' }}
+    if: ${{ github.event.deleted == false && vars.PUSH_EMAIL_ENABLED == 'true' }}

[warning] 13-16: insufficient job-level concurrency limits (concurrency-limits): workflow is missing concurrency setting

(concurrency-limits)

only still-valid issues, skip the rest with a brief reason, keep changes
minimal, and validate.

In @.github/workflows/push-email-notify.yml at line 16, Update the push
notification job condition to require github.event.deleted == false, preventing
branch-deletion pushes from running when github.event.head_commit is null. Keep
the existing branch matching behavior unchanged.

concurrency:
# Deliberately per-RUN, so no run is ever queued behind another and none is
# ever cancelled. Do NOT "tidy" this into a shared group such as
# ${{ github.workflow }}-${{ github.ref }}. GitHub's workflow-syntax docs:
# "By default, any existing pending job or workflow in the same concurrency
# group will be canceled and the new queued job or workflow will take its
# place." That happens regardless of cancel-in-progress, which governs only
# the RUNNING job. On this workflow it silently loses a notification email,
# with no error anywhere. Every run here reports a DISTINCT commit, so there
# is no redundant work for a concurrency limit to remove.
# The docs also offer `queue: max` (up to 100 pending); not used, because 100
# is still a cap whereas a per-run group needs none.
# Verified with zizmor 1.30.0: deleting this block raises concurrency-limits;
# this form silences it exactly as a shared group would.
